HSC mechanics Extension 2 applies calculus and vectors to physical situations — motion under gravity, resisted motion, forces on inclined planes, and projectile trajectories. It is one of the most applied topics in the Extension 2 course.
What to master
- Vector kinematics — displacement, velocity, acceleration as vectors
- Newton's laws applied to particles and connected systems
- Projectile motion — parametric equations, range, maximum height
- Resisted motion — exponential decay models, terminal velocity
- Setting up and solving differential equations from physical models
Free mechanics booklet
HSC Mechanics on Vu's Maths Hub covers vectors, motion, forces, and modelling with projectile motion worked examples and resisted motion HSC questions.

Mechanics relies heavily on:
- HSC Vectors — dot product, cross product, 3D geometry
- HSC Differential Equations — first-order ODEs from physical models
- HSC Integrals — integration techniques for motion problems
